The Dewalt metal drill bit is of the Extreme 2 type. It features the following characteristics:

• Guide/cutting tip that starts drilling on first contact with the material, eliminating slipping for clean and accurate holes (diameters 4.8mm and above only).
• Innovative tapered web structure that significantly reduces the risk of breakage.
• Anti-slip shank with 3 flat surfaces that prevents slipping in the chuck (diameters 5.0mm and above only).
• Permanent size markings above the point where the shank meets the chuck for greater visibility and ease of use (diameters 3.0mm and above only).

The Extreme 2 metal drill bit is designed to maximize drilling performance and offers:

• Faster drilling – up to 4 times faster than standard HSS-R drill bits.
• Increased durability – up to 50% stronger than standard HSS-R drill bits.
• Cleaner and more accurate holes without burrs thanks to the recessed cutting flutes.
